Gaby loves photography.
Her mother, Kristin, is seriously in debt from gambling. Gaby tried to help her with her dept. She doesn't know who the father of her daughter is. Kristin worked as a dancer. When Gaby disappeared her mother got a boyfriend (Yumeko and Michicatsu). She loves Gaby, when she found out what they did to her she took revenge.
As Gaby was leaving work (she works in a restaurant), she was attacked by men to whom her mother owed money. In the process, her phone broke, so she couldn't contact her mother. When she realized this, she started crying because she had many photos saved.
Michael was in a gang when he was young, Tokyo Revengers. He is kind and tries his best to stay out of trouble due to his past; although it may not seem like it, he has little patience.
Michael’s going to college to study medicine and also has a part-time job in a convenience store. His grandmother was his inspiration to become a doctor.
Michael lived with his paternal grandparents since his parents worked a lot and could not take care of him. It can be said that they are wealthy since when Michael decided to leave his grandparents' house, his parents got him an apartment.
One day, when he was still living with his grandparents, he beat a guy up so badly that he almost went to jail for it and his grandmother had an accident in which she almost lost her life. After that, he left the gang and behaved.
Gaby relies on her actions to demonstrate her worth, she developed this after her mother, she thought her mother would abandon her as she did with the man she had. “If she says that she loves them and then leaves them, then why would I be different from them?” She thought like that.
The reason Michael takes care of Gaby is because he studies medicine (is there another reason?).
Gaby stayed in his house for over a week. Michael got used to seeing her every time he came home. She found Michael’s bat and he told her that he was a gang member. “Those days were the freest I’ve ever had.” Gaby showed interest and amazement, so Michael kept talking. When she recovers, she visits him.
At some point in the story, he went to her house and met her mother. Gaby got into an accident and was sent to the hospital.
